Single equivalent discount for two successive discounts of $x \%$ and $y \%$

$=\left(x+y-\frac{x y}{100}ight) \%$

$	herefore \quad$ single equivalent discount for $10 \%$ and $20 \%$

$=\left(10+20-\frac{10 	imes 20}{100}ight) \%=28 \%$

single equivalent discount for $28 \%$ and $50 \%$

$=\left(50+28-\frac{50 	imes 28}{100}ight) \%=(78-14) \%=64 \%$
